First of all, great addon, your time and effort are appreciated by many.
I ran this addon for the first time last night, and holy walnuts, I barely had to lift a finger to manage attendance, it was great. That being said, I found that I needed to keep an editor open in the background so I could jot down short notes about certain attendees: excuses for being late, who went above and beyond for the good of the raid (respec'd for a particular fight), etc. After the raid, I then added those notes to the phpbb output that I archive for each raid.
I didn't see this on the wiki Wish List, so I thought I'd throw it out there. I would love a way to add a short note for a given attendee in the Raid Members pane or Member Information pane, and have that note be included in the exported data.
I have never written an addon, so I have no idea how hard this would be, but thank you for considering and keep up the good work.
